3. Web-based User Interface
3.1 Setting up Connection
This switch can be managed using a standard Web Browser from any computer attached to the network. The
SNMP management feature also permits the switch to be managed from any SNMP network management
station running a network management program. Factory Default value of system is:
IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.254
It supports a simple user management function allowing only one administrator to configure the system
at the same time. If there are two or more users using administrator’s identity, the switch will allow the only one
who logins first to configure the system. The rest of users, even with administrator’s identity, can only monitor
the system. For those who have no administrator’s identity, can only monitor the system. There are only a
maximum of three users able to login simultaneously in the switch. To optimize the display effect, we
recommend you use Microsoft IE 6.0 above, Netscape V7.1 above or FireFox V1.00 above and have the
resolution 1024x768. The switch supported neutral web browser interface.
Login account by default is:
Username: admin Password: admin (read/write)
Username: guest Password: guest (read only)
Here is the whole function tree with web user interface and we will travel it through this chapter.

3.2 Web Management Overview
After you login, the switch shows you the system information as a below. This page is default and tells
you the basic information of the system, including “Model Name”, “System Description”, “Location”, “Contact”,
“Device Name”, “System Up Time”, “Current Time”, “BIOS Version”, “Firmware Version”,
“Hardware-Mechanical Version”, “Serial Number”, “Host IP Address”, “Host Mac Address”, “Device Port”,
“RAM Size” and “Flash Size”. With this information, you will know the software version used, MAC address,
serial number, how many ports good and so on. This is helpful while malfunctioning.
On the top side, it shows the front panel of the switch. In the front panel, the linked ports will display green; as
to the ports, which are link off, they will be dark. For the optional modules, the slot will show only a cover plate
if no module exists and will show a module if a module is present. The image of module depends on the one
you inserted. The same, if disconnected, the port will show just dark, if linked, green.
In this device, there are clicking functions on the panel provided for the information of the ports. These are
very convenient functions for browsing the information of a single port. When clicking the port on the front
panel, an information window for the port will be pop out as below. It shows the basic information of the clicked
port. With this, you’ll see the information about the port status, traffic status and bandwidth rating for egress
and ingress respectively.

3.3.2 IP Configuration
IP configuration is one of the most important configurations in the switch. Without the proper setting, network
manager will not be able to manage or view the device. The switch supports both manual IP address setting
and automatic IP address setting via DHCP server. When IP address is changed, you must reboot the switch
to have the setting taken effect and use the new IP to browse for web management and CLI management.
Parameter description:
yDHCP Setting:
DHCP is the abbreviation of Dynamic Host Configuration Protocol. Here DHCP means a switch to turn
ON or OFF the function. The switch supports DHCP client used to get an IP address automatically if
you set this function “Enable”. When enabled, the switch will issue the request to the DHCP server
resided in the network to get an IP address. If DHCP server is down or does not exist, the switch will
issue the request and show IP address is under requesting, until the DHCP server is up. Before getting
an IP address from DHCP server, the device will not continue booting procedures. If set this field
“Disable”, you’ll have to input IP address manually.
yIP address:
Users can configure the IP settings and fill in new values if users set the DHCP function “Disable”.
Then, click <Apply> button to update. When DHCP is disabled, Default: 192.168.1.1. If DHCP is
enabled, this field is filled by DHCP server and will not allow user manually set it any more.
ySubnet mask:
yDefault gateway:
Set an IP address for a gateway to handle those packets that do not meet the routing rules predefined
in the device. If a packet does not meet the criteria for other pre-defined path, it must be forwarded to a
default router on a default path. This means any packet with undefined IP address in the routing table
will be sent to this device unconditionally. Default: 192.168.1.254.
yDNS:
It is Domain Name Server used to serve the translation between IP address and name address. The

12
switch supports DNS client function to re-route the mnemonic name address to DNS server to get its
associated IP address for accessing Internet. User can specify a DNS IP address for the switch. With
this, the switch can translate a mnemonic name address into an IP address. There are two ways to
specify the IP address of DNS. One is fixed mode, which manually specifies its IP address, the other is
dynamic mode, which is assigned by DHCP server while DHCP is enabled. DNS can help you easily
remember the mnemonic address name with the meaningful words in it. Default is no assignment of
DNS address. Default: 0.0.0.0
3.3.3 Time Configuration
The switch provides manual and automatic ways to set the system time via NTP. Manual setting is simple and
you just input “Year”, “Month”, “Day”, “Hour”, “Minute” and “Second” within the valid value range indicated in
each item. If you input an invalid value, for example, 61 in minute, the switch will clamp the figure to 59.
NTP is a well-known protocol used to synchronize the clock of the switch system time over a network. NTP, an
internet draft standard formalized in RFC 1305, has been adopted on the system is version 3 protocol. The
switch provides four built-in NTP server IP addresses resided in the Internet and an user-defined NTP server
IP address. The time zone is Greenwich-centered which uses the expression form of GMT+/- xx hours.
Parameter description:
yCurrent Time: Show the current time of the system.
yManual:
This is the function to adjust the time manually. Filling the valid figures in the fields of Year, Month, Day,
Hour, Minute and Second respectively and press <Apply> button, time is adjusted. The valid figures for
the parameter Year, Month, Day, Hour, Minute and Second are >=2000, 1-12, 1-31, 0-23, 0-59 and
0-59 respectively. Input the wrong figure and press <Apply> button, the device will reject the time
adjustment request. There is no time zone setting in Manual mode.
yNTP:
NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean Time
(GMT). If use the NTP mode and select a built-in NTP time server or manually specify an user-defined

13
NTP server as well as Time Zone, the switch will sync the time in a short after pressing <Apply> button.
Though it synchronizes the time automatically, NTP does not update the time periodically without
user’s processing.
Time Zone is an offset time off GMT. You have to select the time zone first and then perform time sync
via NTP because the switch will combine this time zone offset and updated NTP time to come out the
local time, otherwise, you will not able to get the correct time. The switch supports configurable time
zone from –12 to +13 steps 1 hour.
Default Time zone: +8 Hrs.
yDaylight Saving:
Daylight saving is adopted in some countries. If set, it will adjust the time lag or in advance in unit of
hours, according to the starting date and the ending date. For example, if you set the day light saving
to be 1 hour. When the time passes over the starting time, the system time will be increased one hour
after one minute at the time since it passed over. And when the time passes over the ending time, the
system time will be decreased one hour after one minute at the time since it passed over.
The switch supports valid configurable day light saving time is –5 ~ +5 step one hour. The zero for this
parameter means it need not have to adjust current time, equivalent to in-act daylight saving. You don’t
have to set the starting/ending date as well. If you set daylight saving to be non-zero, you have to set
the starting/ending date as well; otherwise, the daylight saving function will not be activated.
Default for Daylight Saving: 0.
The following parameters are configurable for the function Daylight Saving and described in detail.
Day Light Saving Start:
This is used to set when to start performing the day light saving time.
Mth:
Range is 1 ~ 12.
Default:1
Day:
Range is 1 ~ 31.
Default: 1
Hour:
Range is 0 ~ 23.

3.3.4 Account Configuration
In this function, only administrator can create, modify or delete the username and password. Administrator can
modify other guest identities’ password without confirming the password but it is necessary to modify the
administrator-equivalent identity. Guest-equivalent identity can modify his password only. Please note that you
must confirm administrator/guest identity in the field of Authorization in advance before configuring the
username and password. Only one administrator is allowed to exist and unable to be deleted. In addition, up to
5 guest accounts can be created.
The default setting for user account is:
Username:admin
Password:admin
The default setting for guest user account is:
Username: guest
Password: guest
3.3.5 Management Policy
Through the management security configuration, the manager can control the mode via which user access
this switch. According to the mode, users can be classified into two types: Those who are able to connect to
the switch (Accept) and those who are unable to connect to the switch (Deny). Some restrictions also can be
placed on the mode that the user connect to the switch, for example, we can decide that which VLAN VID is
able to be accepted or denied by the switch, the IP range of the user could be accepted or denied by the
switch, the port that the user is allowed or not allowed to connect with the switch, or the way of controlling and
connecting to the switch via Http, Telnet or SNMP.

15
Parameter description:
yName: A name is composed of any letter (A-Z, a-z) and digit (0-9) with maximal 8 characters.
yVID:
The switch supports two kinds of options for managed valid VLAN VID, including “Any” and “Custom”.
Default is “Any”. When you choose “Custom”, you can fill in VID number. The valid VID range is
1~4094.
yIP Range:
The switch supports two kinds of options for managed valid IP Range, including “Any” and “Custom”.
Default is “Any”. In case that ”Custom” had been chosen, you can assign effective IP range. The valid
range is 0.0.0.0~255.255.255.255.
yIncoming Port:
The switch supports two kinds of options for managed valid Port Range, including “Any” and “Custom”.
Default is “Any”. You can select the ports that you would like them to be worked and restricted in the
management security configuration if ”Custom” had been chosen.
yAccess Type:
The switch supports two kinds of options for managed validAccess Type, including “Any” and
“Custom”. Default is “Any”. “Http”, “Telnet” and “SNMP” are three ways for the access and managing
the switch in case that” Custom” had been chosen.
yAction:
The switch supports two kinds of options for managed valid Action Type, including “Deny” and “Accept”.
Default is “Deny”. When you choose “Deny” action, you will be restricted and refused to manage the
switch due to the “Access Type” you choose. However, while you select “Accept” action, you will have
the authority to manage the switch.
yEdit/Create:
A new entry of Management Security Configuration can be created after the parameters as mentioned
above had been setup and then press <Edit/Create> button. Of course, the existed entry also can be
modified by pressing this button.
yDelete: Remove the existed entry of Management Security Configuration from the management
security table.
3.3.6 Virtual Stack
Virtual Stack Management (VSM) is the group management function. Through the proper configuration of this
function, switches in the same LAN will be grouped automatically. And among these switch, one switch will be
a master machine, and the others in this group will become the slave devices.
VSM offers a simple centralized management function. It is not necessary to remember the address of all
devices; manager is capable of managing the network with knowing the address of the Master machine.
Instead of SNMP or Telnet UI, VSM is only available in Web UI. While one switch becomes the Master, two
rows of buttons for group device will appear on the top of its Web UI. By pressing these buttons, user will be
allowed to connect the Web UI of the devices of the group in the same window without the login of these
devices.

16
Parameter description:
yState: It is used for the activation or de-activation of VSM. Default is Enable.
yRole: The role that the switch would like to play in virtual stack. Two types of roles, including master
and slave are offered for option. Default is Master.
yGroup ID: It is the group identifier (GID) which signs for VSM. Valid letters are A-Z, a-z, 0-9, “ - “ and
“_” characters. The maximal length is 15 characters.
The most top-left button is only for Master device. The background color of the button you press will be
changed to represent that the device is under your management.
Note: It will remove the grouping temporarily in case that you login the switch via the console.
The device of the group will be shown as station address (the last number of IPAddress) + device name on
the button (e.g. 1_SP1684F), otherwise it will show ” ---- “ if no corresponding device exists.
Once the devices join the group successfully, then they are merely able to be managed via Master device, and
user will fail to manage them via telnet/console/web individually.
Up to 16 devices can be grouped for VSM, however, only one Master is allowed to exist in each group. For
Master redundancy, user may configure more than two devices as Master device; however, the Master device
with the smaller MAC value will be the Master one. All of these 16 devices can become Master device and
back up with each other.
3.4 Port configuration
Four functions, including Port Status, Port Configuration, Simple Counter and Detail Counter are contained in
this function folder for port monitor and management. Each of them will be described in detail orderly in the
following sections.
3.4.1 Status
The function Port Status gathers the information of all ports’ current status and reports it by the order of port
number, link status, port state, Auto-Negotiation status, speed/duplex and flow control. Extra media type
information for the module ports 9 to 24 is also offered. It reports the latest updated status of all ports in this
switch. When any one of the ports in the switch changes its parameter displayed in the page, it will be
automatically refreshed the port current status about every 5 seconds.

17
Parameter description:
ySlot No.:
Display the slot number. The number is 1 – 3.
yPort No:
Display the port number. The number is 1 – 26. Both port 25 and 26 are optional modules.
yMedia:
Show the media type adopted in all ports. The Port 25 and Port 26 are optional modules, which
support either fiber or UTP media with either Gigabit Ethernet (1000Mbps) or 10/100Mbps Fast
Ethernet port. They may have different media types and speed. Especially, fiber port has
comprehensive types of connector, distance, fiber mode and so on. The switch describes the module
ports with the following page.
yLink:
Show that if the link on the port is active or not. If the link is connected to a working-well device, the
Link will show the link “Up”; otherwise, it will show “Down”. This is determined by the hardware on both
devices of the connection.
No default value.
yState:
Show that the communication function of the port is “Enabled” or “Disabled”. When it is enabled, traffic
can be transmitted and received via this port. When it is disabled, no traffic can be transferred through
this port. Port State is configured by user.
Default: Enabled.
yAuto Negotiation:
Show the exchange mode of Ethernet MAC. There are two modes supported in the switch. They are
auto-negotiation mode “Enabled” and forced mode “Disabled”. When in “Enabled” mode, this function
will automatically negotiate by hardware itself and exchange each other the capability of speed and
duplex mode with other site which is linked, and comes out the best communication way. When in
“Disabled” mode, both parties must have the same setting of speed and duplex, otherwise, both of
them will not be linked. In this case, the link result is “Down”.

18
Default: Enabled
ySpeed / Duplex Mode:
Display the speed and duplex of all port. There are three speeds 10Mbps, 100Mbps and 1000Mbps
supported for TP media, and the duplex supported is half duplex and full duplex. If the media is 1Gbps
fiber, it is 1000Mbps supported only. The status of speed/duplex mode is determined by 1) the
negotiation of both local port and link partner in “Auto Speed” mode or 2) user setting in “Force” mode.
The local port has to be preset its capability.
In port 1 – 24, they are supported Fast Ethernet with TP media only, so the result will show 100M/Full
or 100M/Half, 10M/Full and 10M/Half duplex.
In port 25 and port 26, if the media is 1000Mbps with TP/SFP media, it will show the combinations of
10/100M and Full/Half duplex, 1000Mbps and Full duplex only. If the media is 1000Mbps with fiber
media, it will show only 1000M/Full duplex.
Default: None, depends on the result of the negotiation.
yRx Pause:
The way that the port adopts to process the PAUSE frame. If it shows “on”, the port will care the
PAUSE frame; otherwise, the port will ignore the PAUSE frame.
Default: None
yTx Pause:
It decides that whether the port transmits the PAUSE frame or not. If it shows “on”, the port will send
PAUSE frame; otherwise, the port will not send the PAUSE frame.
Default: None
Parameter description of Port 25 and Port 26:
